A rhinestone is made of flint glass with an index of refraction of 1.50. To make it more reflective, it is coated with a thin film of Si0 that has a refractive index of 2.00. Find the first two possible thicknesses of the SiO coating that provide strong reflection for 570 nm light at normal incidence.

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.

Iwould say earthquakes.
